YOKNEAM, Israel — (BUSINESS WIRE) — July 13, 2011 —
EZchip Semiconductor Ltd. (NASDAQ:
EZCH), a leader in Ethernet network
processors, today announced that the latest OpenFlow spec, version 1.1,
has been successfully implemented on the NP-4 network processor by
several independent bodies. OpenFlow is a protocol that allows
separation of the data and control planes in a switched network and
seeks to increase network functionality while lowering the cost
associated with operating networks. Leading hardware, software and
service provider companies are members of the recently formed Open
Networking Foundation, a nonprofit organization that promotes OpenFlow.

One of the implementations of OpenFlow 1.1 on the NP-4 was developed by
the Telecom Research Team (LTIR Lab) at the Université du Québec à
Montréal (UQAM), while others are at corporations that prefer
confidentiality. The LTIR Research Lab was founded by Professor Omar
Cherkaoui who is leading a major project on the virtualization of
network equipment called Netvirt.

“EZchip’s NP-4 processor provides the flexibility and performance
necessary for implementing OF1.1 as well as any future versions of the
standard. NP-4’s easy programming model enabled the UQAM Netvirt team to
realize our OF1.1 full implementation with a high level of flexibility
and a full 100 Gigabits. We are very pleased with the outcome,” said
Prof. Omar Cherkaoui, Université du Québec à Montréal.

While the previous version of OpenFlow, version 1.0, has seen multiple
silicon-based implementations, the recently released version 1.1 strains
silicon implementations by requiring a high degree of packet processing
flexibility, in particular performing repetitive nested lookups in
various tables. EZchip’s network processors (NPUs) have long been
recognized as providing a great degree of packet processing flexibility
through software programming and without requiring any special hardware
enhancements or revisions, EZchip’s NPUs enable high performance
implementation of the OpenFlow version 1.1 protocol, demonstrating the
reduced time-to-market coupled with high-performance benefits provided
by EZchip’s NPUs.
